Time will tell, but I don't think so. There's still a strong demand for the GR. That's something the Coolpix A never had. I bet Nikon will discontinue the A before Ricoh discontinues the GR.

Don't be too sure. Amazon and B&H still have the GR in stock but Adorama doesn't, and instead of saying "Out of stock", they show no price and say "We’re sorry, this item is no longer available."

It's hard to tell whether the GR was a big success or not much of a success, despite a general assumption that it was selling well. But the GR LE was supposedly limited to 5,000 copies, worldwide, sold directly by Pentax/Ricoh. Yet after a month they started appearing from many camera dealers in the USA, Canada and the UK, so unless Ricoh wasn't being honest and produced more than the claimed 5,000, the GR LE didn't sell as well as Ricoh assumed it would.

The only positive I can see from this is that there may soon be a GR VI in the works. If so, I wonder if it will use the same lens. It would be interesting to see a GR with a 21mm or a 35mm lens, but that would be a real tradition changer. A 21mm version would probably be more popular with DSLR owners.
